Matthew 5:24 leave your gift there in front of the altar. First go and be reconciled to them; then come and offer your gift.
God is not looking for the most expensive gift you can possible afford to give Him. He is not looking for something which will leave you with nothing.
He wants something you give from the heart.
Which means we need to look at the other things and people in our lives and see if we are short changing them just to give to God. When we do that we are working against Him because we all are His!
